    Tx 32 l z d 80 panasonic tv , no hdmi signal

    Hi all

    As per the title , there's no signal via any of the 3 HDMI ports .

    Have inspected all 3 ports under magnification & no signs of damage .

    Checked the S M D components leading off from port pins & again seem good .

    TV works fine via free view channels , and s c a r t ports .

    My prime suspect is the HDMI processing chip I C 4510 .

    It's manufactured by A n a l o g Devices . Type ADV 6495 B B S T Z - 170 .

      Managed to find a different Panasonic board in stock , that uses the same chip .

      Swapped it into the customers board , & success .

      On test via HDMI 1 at the moment & working well .

      Will test out other ports , then report back .

          PS4 fat has inconsistent signal after HDMI replacement
          by supravit2000
          Hi, guys!

          I am not a professional, all I can do is solder stuff on the boards, so I would really appreciate it if someone with knowledge shares his experience/thoughts on a problem I have with a PS4 console.

          My friend gave me an original fat PS4, board model SAB-001, with WLOD, that has been previously opened. I changed the HDMI port, couple of pads on the board were ripped, which I connected to the corresponding caps/resistors? Just did so as in a shown diagram (one of the ground pads I ripped off and left it not connected). However, there was still no signal, so...

          Samsung UE65MU7003U / BN41-02568B - HDMI No Signal
          by natiz
          Following a power surge, the HDMI ports on a UE65MU7003U no longer work, no matter the port or the source - it shows No Signal.
          The other functions work well (eg Netflix app, etc.), its just the HDMI ports.

          Is the BN41-02568B board salvageable? Any leads before I open the heatsink cover? board replacement?...

          PS5 HDMI not outputting CK/DA Signal
          by Comp_Pro
          Hello all,

          I am trying to repair this PS5 which came in with a shorted HDMI encoder chip. This issue was not allowing the PS5 to boot and would only beep upon pressing the power button. This is the first time I've had this issue despite replacing many many HDMI ports. After installing the new chip as well as a new HDMI port the console now powers on and appears to be booting all the way but there is no video output. Looking at my HDMI tester all signals are present except for DCC Clock and DCC Data aka CK/DA on my particular tester. These two have direct connections to the encoder...

          HDMI ports not working - Panasonic model number TX-P50XT50B 50"
          by BadTelly
          Hi,

          Suddenly all HDMI ports stopped working on a Panasonic 50" TV. This is model number TX-P50XT50B and has worked fine for years.

          The TV turns on but no joy on either HDMI-1 or HDMI-2 and I've tested it using an input device and cable that works fine on another TV via HDMI.

          Thank you in advance for any help/ advice.

          Kind regards,

          Bad Telly
